Oracle DR: Convert restore scripts to PowerShell for SSH compatibility

- Add cleanup_database.ps1: PowerShell version without input redirection issues
- Add rman_restore_from_zero.ps1: PowerShell version with inline SQL commands
- Update weekly-dr-test-proxmox.sh: Call .ps1 scripts via PowerShell

PowerShell scripts resolve SSH 'Input redirection not supported' errors
All SQL commands are piped directly to sqlplus (no temp files needed)
